Oulipo: can't change link size

I'm new to WordPress and have no idea what I'm doing with CSS (I bought the full customization package, though, so I can learn), and I'm using the Oulipo template. All is well so far, but when I add a link to my text, it makes that text much smaller than everything else. No matter what size I set the basic text at, the size of the links stays the same. Can I change this?

(I've noticed people have put ideas out there for how to override small caps, but those overrides don't seem to work on this problem...)
